Hej igen. Synes iøvrigt det er en god idé med flasken indeni flasken.
Ja, en REPRAP skal vel have en arbejdstegning. Du kunne evy støbe i plast. Polyetylen smelter nemt og er velegnet. Så en gipsafstøbning af den tut du har og så smelte plast ned i.
Kigger måske forbi og ser din opstilling; men har en halv aftale med en, så det er ikke sikkert idag.In reply to - René Mikkelsen posted an update in the group Denmark: Er der nogen der ved hvor man i KBH eller på nettet i Danmark kan købe noget lignende med dem her: http://our.windowfarms.org/instructions_dev/images/6_29.jpg Lige nu bruger jeg en ventil-stang fra en racerventil, men jeg vil gerne have fat i noget der lukker lidt mere vand igennem og som jeg også [...] · View -

Hej igen René. Man kan jo købe plastiktutter til regnvandstønder; men de er nok ret brede i det?

Hej René. Har ikke set sådanne – og er ikke helt klar på hvor i systemet du vil bruge dem. Men generelt tror jeg metaller i kontakt med vandet er en dårlig idé. V il nok kigge forbi LABITAT og se hvad du har gang i. :0)

Hi again Bobby
I know that. Had that problem in my fish-tank-system and placed an airpump in the aquarium – just in case. I didn´t clean it and after a month it started to work by it self again. Some of the problem was air-build-up at the top in some of the hoses I use, which stalled the waterflow.Eggshells and coffee/tea I´ve been using for years – and shells from the beach too.
Dried seaweed is also very good!Best Regards

How strong ammonia??? We have two here in Dk: a 8% (I think) and one with about 30%.

In a video about growing spirulina I saw one who just placed a sack with straw in a tank through which the water ran in the system. This gave off both carbondioxide an other nutrients as it decayed. -

You could make some kind of system like this:

(The aquarium-pump under “Ecology”)
It has been running for more than 20 months now!Best regards

Maybe it´s just me, but I would NEVER use aluminum in contact with water for any kind of plants/aquariums. Aluminum will replace magnesium whiich is essential in clorophyl! Further, it will accumulate in your body and is considered toxic.
Best regards

i want to challenge this, just for clarification.

cool idea, I haven’t heard of that before. Take extra precaution when you’re cleaning your system out- with all that decomposition, you may be bound to get backed up in your systems plumbing.
btw, what i’ve found to work for my winter plants is to have decomposed coffee and egg shells mixed with 5 ml ammonia (5% approx)- I’ve also thrown in some organic fertilizer i found in my garage (hmm). anyways, it’s been doing wonders even for the cold on cleveland, oh.
best of luck,

Cyanobacteria fixes nitrogen into the media. My friend is working on research to process them into biofuels.
